Ratio Tables and Proportions 2

Front

What is a ratio?

Back

A ratio is a comparison of two quantities by division, showing how many times one value contains or is contained within the other.

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

How do you find equivalent ratios?

Back

To find equivalent ratios, you can multiply or divide both terms of the ratio by the same non-zero number.

Front

What is a ratio table?

Back

A ratio table is a table that displays pairs of numbers that form equivalent ratios.

Front

How do you determine the missing value in a ratio table?

Back

To determine the missing value, use equivalent ratios or cross-multiplication.

Front

What is the slope of a line in a linear equation?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x.

Front

What does the slope-intercept form of a linear equation look like?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you write an equation from a ratio?

Back

To write an equation from a ratio, express the relationship between the two quantities in the form of y = kx, where k is the constant of proportionality.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the factor that relates two proportional quantities, often represented as k in the equation y = kx.

Front

How can you check if two ratios are equivalent?

Back

To check if two ratios are equivalent, cross-multiply and see if the products are equal.
